IMPROVEMENT N TIEIRIEISHIlTG-ll/II-LCHINES.4

4The Schedule referred to'in these Letters PatentV and making part o! the same To all whom it may concern Be it known that I, GEORGE B. HAMLIN, of Willimantic, in the town of' lVindham, county of Windham, in the State of Connecticut, have invented a new and useful Improvement in Threshing-lvIachincs; and I do hereby declare that the following is a full, clear, and'exact description thereof, which. will enable others skilled in the art to malte and use the same, reference being had to the accompanying drawings forming part of this specification, in which-` Figure l represents, in end View, a cylinder with one iiail arm, illustrating my improvement.

Figure 2 represents :t cylinder in trat-ing more fully my invention, showing the position of the several fiail arms.

Figures 3 and 4 repl'esent, on a larger scale, my iinproved ilail arm.

,Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of threshing cylinders and rotating teeth 01 beaters, so as to make them more eiiicient in use and less liable to get ontfoil order,'or'to be broken, than wheuconstructed in the ordinary manner; and l It consists in the construction and combination of the above-named parts, as hereinafter more fully derscribed.

A represents the pulley or cylinder, forming a drum or shell, attached to the shaft .by one set of arms C, in the center of' the sanne, making it easy of access when needing repairs, and preventing the winding of` perspective, illuse straw between the arms and frame, so prevalent in ordinary machines.

B are teeth or beaters, which pass through small orifices in the drum or shell A, with circular heel attached to the inner surface of said drum A by lugs or other means, the circle being'so formed as to pass in a direct lille through the small orifice in the drum A,

when they are thrown forward at right angles by the certrifugal force until the force of the blow is imparted to the grain, when they are rapidly folded baci; with- `out impeding the revolutions of' the cylinder.

By this combination the drum or pulley presents a ,smooth surface to the action of the straw, preventing `the throwing back the grain and straw by the adhesion of the same to the rough surface of ordinary cylinders.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The curved tlail arms or beaters B, passing through suitable apertures in the shell oi' the cylinder, and attached by a hinge joint, or its equivalent, to the interior of the cylinder, substantially asvshown and described, for the purposes specified.

The above specificationo my invention signed by me this 29th day of Sepemher, 1869.

GEORGE B. HAMLIN.
